URI Parameters

Name	In	Required	Type	Description
endpoint	path	True	string	The endpoint URL of the search service.
indexName	path	True	string	The name of the index.
api-version	query	True	string	Client Api Version.
search	query	True	string	The search text to use to suggest documents. Must be at least 1 character, and no more than 100 characters.
suggesterName	query	True	string	The name of the suggester as specified in the suggesters collection that's part of the index definition.
$filter	query		string	An OData expression that filters the documents considered for suggestions.
$orderby	query		string[]	The list of OData $orderby expressions by which to sort the results. Each expression can be either a field name or a call to either the geo.distance() or the search.score() functions. Each expression can be followed by asc to indicate ascending, or desc to indicate descending. The default is ascending order. Ties will be broken by the match scores of documents. If no $orderby is specified, the default sort order is descending by document match score. There can be at most 32 $orderby clauses.
$select	query		string[]	The list of fields to retrieve. If unspecified, only the key field will be included in the results.
$top	query		integer int32	The number of suggestions to retrieve. The value must be a number between 1 and 100. The default is 5.
fuzzy	query		boolean	A value indicating whether to use fuzzy matching for the suggestions query. Default is false. When set to true, the query will find terms even if there's a substituted or missing character in the search text. While this provides a better experience in some scenarios, it comes at a performance cost as fuzzy suggestions queries are slower and consume more resources.
highlightPostTag	query		string	A string tag that is appended to hit highlights. Must be set with highlightPreTag. If omitted, hit highlighting of suggestions is disabled.
highlightPreTag	query		string	A string tag that is prepended to hit highlights. Must be set with highlightPostTag. If omitted, hit highlighting of suggestions is disabled.
minimumCoverage	query		number double	A number between 0 and 100 indicating the percentage of the index that must be covered by a suggestions query in order for the query to be reported as a success. This parameter can be useful for ensuring search availability even for services with only one replica. The default is 80.
searchFields	query		string[]	The list of field names to search for the specified search text. Target fields must be included in the specified suggester.
